Open Cooling Tower XE-OCT-250T

Structural Materials

• Standard Structural Materials
The industry's highest specification G235 galvanized steel is used to ensure a longer cooling tower life. The cooling tower equipment is a frame structure with higher strength. The 1000 series standard structure has been tested by an independent third-party vibration table, with an SDS of 1.4g and a wind resistance of 60psdf. With regular maintenance and water treatment, the G235 galvanized steel frame structure, panels and air inlet louvers have a long service life and meet the requirements of various comfort air conditioning and industrial applications.

• Stainless steel material (optional)
Type 304 stainless steel structural materials are available.

• No water collection plate structure (optional)
The 1000 series cooling tower can be selected as a water-free structure, which can be placed directly on a new or existing concrete pool. This option eliminates the need for a cold water pan and reduces maintenance costs. When installing multiple units, it can simplify the requirements for piping and water pumps, and provide a cost-effective method to replace the water tower. It is a leading evaporative cooling manufacturer and supplier of water-free structures.

• Higher earthquake and wind resistance level structure (optional)
Upgraded steel panels and structural parts to meet higher earthquake and wind resistance requirements. The upgraded 1000 series SDS reaches 3.10g and the wind resistance level reaches 82psf. All upgraded equipment has been tested on the vibration table of the test bench to ensure that it can continue to operate in earthquake conditions.

• Standard galvanized steel panels and air inlet louvers
The sturdy frame structure is equipped with galvanized steel panels and air inlet louvers to enhance the equipment's corrosion resistance and extend its service life.

• Stainless steel/FRP panels and air inlet louvers (optional)
A variety of panels and air inlet louvers are available, including stainless steel and FRP.



Product introduction

①Structural system

• Tower metal components: The tower body is made of 304 stainless steel or Baosteel hot-dip galvanized steel plate, which is light in weight and has good rigidity. All material indicators meet relevant national standards. The parts are highly interchangeable, easy to assemble, and have good stability. They can operate normally for a long time in harsh environments.
• Tower surface components: high-quality steel, rust-free for a long time, beautiful appearance, integrated with modern architecture.

②Heat exchange system

• Flame retardant heat dissipation filler:

1) It is made of high-quality modified PVC sheets that are resistant to ultraviolet rays and chemical corrosion through fully automatic vacuum forming, and its performance indicators meet the requirements of NDG88-89 "Technical Regulations for Plastic Water-Spraying Fillers".

2) The filler has good flame retardant properties. The oxygen index of the filler is tested to be 38, which is much higher than the national standard requirement of ≥28.

3) The water-spraying filler is designed in an inverted "V" shape and is assembled in blocks inside the tower, which avoids compression deformation of the filler due to fouling. The assembled filler has the dual functions of heat dissipation and water collection. The large-particle spacing structure ensures that the filler is not blocked, which not only reduces wind resistance but also reduces the chance of biological derivation.

4) The large "honeycomb" structure design has a diversion effect and has a good uniform air distribution effect, which improves and stabilizes the heat exchange intensity of water vapor. The precise positioning and equal spacing combination facilitates the formation of a large area of ​​flowing water film with the water flowing through the surface, thereby promoting water vapor exchange.

• Special water collection structure: Made of high-quality PVC material, it is the leading one in the domestic industry. It can effectively separate the water vapor in the hot and humid air and return it to the tower, greatly reducing the loss of floating water and the amount of make-up water. The floating water loss rate of LKN series cooling tower is less than 0.001%.
• Variable diameter graded nozzle: The watering system uses the nozzle produced by introducing new technology from the United States as the main component. The nozzle is made of high-quality modified P.P. injection molding, has no moving parts inside, and is corrosion-resistant and aging-resistant. It has low energy consumption during operation, and the design of inner circle and outer square is not easy to be blocked, does not need to be cleaned, and reduces the workload of maintenance.

③Drive system

• Fan: It is a low-speed space-distorted forward-inclined aluminum alloy cooling tower fan. It has the advantages of low noise, large air volume, high efficiency, low power consumption and stable operation.
• Motor: A fully enclosed, self-cooling, low-noise cooling tower motor is used. Protection level IP44, insulation level B, 380 (V) /34/50 (HZ). Small size, light weight, vertical installation, simple positioning, good starting performance, reliable operation, and convenient maintenance. The motor shaft waterproof rubber ring, junction box waterproof rubber pad, and special drainage holes on the mounting seat designed for hot and humid environments ensure that the motor is not soaked and runs without damage for a long time.
• Motor frame: adopts international design concept, positioned once on the tower steel structure frame, with few parts, easy installation, good rigidity, small vibration, high stability, not affected by glass fiber aging, and not easy to damage transmission parts.
• Reducer: Equipped with high-precision imported bearings, three-layer safety oil seals, good waterproof performance, to prevent water vapor from corroding the bearings. Disc-shaped steel seat support and cast iron plate pulley design, compact structure, with static balance check, stable operation, low noise. Special inverted installation, easy maintenance, noise and life are better than similar products, reducer design with maintenance nozzle, easy daily maintenance.
• Belt: We use Japanese high-efficiency and strong V-belt, which is made of excellent polymerized thermoplastic elastic material. It is wear-resistant, oil-resistant, water-resistant, and aging-resistant, has good flexural performance, is not easy to elongate, has good running stability, and has a long service life.

④Additional system

• Air duct: The special streamlined air inlet and precise blade air duct gap allow the air flow to enter the air duct smoothly, avoiding the generation of vortex and reducing the energy consumption of the fan. The air duct is equipped with a diffusion silencer, which reduces the wind speed at the air outlet, reduces kinetic energy loss, saves energy, reduces the reflux of humid and hot air, and reduces noise. The air duct adopts a modular design, which is easy to assemble.
• Water replenishment: The water replenishment ball valve is installed on the inclined bottom basin, which is convenient for adjusting the water replenishment and observing the water level in the bottom basin. The inclined bottom basin design is conducive to the cleaning and drainage of the bottom basin.
